3 Configuring IP addresses

NOTE

You must set the super-user password before you can set other types of passwords.

4. Enter the following commands to set the port configuration and read-only passwords:

BigIron RX(config)# enable port-config-password <text>

BigIron RX(config)# enable read-only-password <text>

Syntax: enable super-user-password read-only-password port-config-password <text>

Passwords can be up to 48 characters long.

Configuring IP addresses

The BigIron RX Series switches implement separate data and control planes. This architecture affects how you assign IP addresses. Table 14 outlines the interfaces to which you can assign IP addresses.

In this table, “in band” refers to an interface over which user packets are routed, while “out of band” refers to an interface over which control packets related to system management are forwarded.

TABLE 14	Assigning IP addresses
Interface		Associated physical port	Out of band or
			in band
Management interface		Ethernet 10/100/1000 port on active or	Out of band
		redundant management module
Any interface over which user packets		Any interface module port	In band
are routed
Any virtual interface over which user		Any interface port	In band
packets are routed
Loopback interface		–	In band

•How to assign an IP address to an interface or virtual interface over which user packets are routed

Support of sub-net masks

The BigIron RX Series switch supports both classical IP network masks (Class A, B, and C sub-net masks, and so on) and Classless Interdomain Routing (CIDR) network prefix masks.

•To enter a classical network mask, enter the mask in IP address format. For example, enter “209.157.22.99 255.255.255.0” for an IP address with a Class-C sub-net mask.

•To enter a prefix number for a network mask, enter a forward slash ( / ) and the number of bits in the mask immediately after the IP address. For example, enter “209.157.22.99/24” for an IP address that has a network mask with 24 significant (“mask”) bits.
